SHOCKING ATTACHMENT FOR BINDERS.

To all whom it may concern.- Be it known that I, WILLIAM HU'MPHREY PERRIN, of the township of Harley, in the district of Nipissi'ng, Province of Ontario, Canada, have invented certain new and useful Improvements in Shocking Attachments for Binders, of which'the following is a specifi c ona 1 h/Iyinventionrelates to improvements in I shocking attachments for binders; and the ob jects of my invention are to devise a'mechanism which may be readily attached to any ordinary form of grain-binder and which will be operated by the mecha'nismof the binder in such a manner that the sheaves of'grain as they are thrown from the binder will be caught and held by the shocking attachment until a given number of them have been collected, when they will all be dropped to the ground '20 in an upright position, supporting each other in a'shock or stook, further objects being to make my device extremely simple in operation andadjustable in its various mechanisms; and it consists, essentially, of a plurality "of pivoted-forms, each supported by two arms carried by an intermittently-revolving part, such revolving part being held on a substantially vertical shaft, which is supported from the frame of the binder by suitable means, 3 means being further provided whereby a driving mechanism of the knotter of the binder. will intermittently revolve the forks through determined distances, whereby as each sheaf is ejected from the binder a fork will be in such'a position as to catch the sheaf and will then support it until all-the forks have caught their respective sheaves,-the device being provided with further means whereby a trip mechanism will then operate to release all the I 4 sheaves together and drop'them to the ground in anupright position, the various details of the device being constructedand arranged as hereinafter more'particularly described.

ates the forks. Fig: 6 is a side view of the stationary and'movable collars on the shaft. Fig. 7 shows a longitudinal view of the knot-,

ter-shaft 0, showing the position of the arms e and f thereon.

In the drawings like characters of reference indicate corresponding parts in each figure.

Referring to Fig. 1, a is the table of the binder, down which the grain passes while it is being formed into the sheaf and tied by the 5 knotting mechanism, partly-shown at b. The details of this knotting mechanism need not be described here, as its construction is well known to anyone skilled in the art. It may, however, be mentioned that a shaft 0 is ro- 7 tated in the direction indicated bythe arrows in Figs. 1 and 4 by suitable means to operate the knotting mechanism. This shaft is journaled in'a bearing formed in a strong casting d, which is secured to or formed integral with the frame of the machine.

At or near the inner extremity of the shaft 0 an arm 6 is provided which in rotating engages the head ends of the sheaves and forces them first down the sloping table and finally 8Q raises the heads of the sheaves with an upward throw at the moment when they are falling from the table.

A second arm f is secured to the shaft and rotates therewith. This arm is provided with 5 an extension g, which is pivotally secured to the main portion at h. The extension g has a projectingpart 21, which extends at an angle therefrom and is provided at its extremity with a roller j. This roller as the shaft ro tates comes in contact with the surface of a cam 70, this cam being secured to any suitable part of the binder, but preferably to a pair of rods 1 1, which are generally used as braces for the shaft 0, As long as the roller is in contact with the cam is it will be seen that the pivoted portion g of the arm f will be kept rigid, so that it will force the 'lower ends of the sheaves forward down the slope of the table a. At the moment when the sheaf is leaving the table, however, the roller j runs ofl. the end of the cam, so that the arm f has no effect in forcing the lower portion of the sheaf any farther, and the result is that the sheaf isthrown off the tablewith the head end up and the stalk end down in a position ready to be caught by the mechanism to be described'hereinafter. Referring to Figs. 1, 2, and 3, it will be seen that-I have provided a vertical shaft m, which is-supported from the frame of the binder by a suitable support a, which is clamped to the casting d or otherwise secured by any suitable means.

0 0 0 0 are forks. Each of these forks is pivoted at its end to arms p and at a pointintermediate of its ends to an arm 9. The arms 19 are pivoted in proximity to their upper extremities by suitable means to projections r, extending outwardly from a rotatable block 8, which is carried by the shaft m. Rollerst are provided at or near the ends of the arms 29 and are adapted to engage a stationary cam a, which is secured to the upright shaft m rigidly by a pin 1; or other suitable means and forms a support for the block 8.

The form of the cam a is shown in Fig. 5, and the object thereof will be hereinafter described. The upper surface of the block 8 is provided with ratchet-teeth 21), which correspond in number to the number of forks carried by the device. .A ratchet-disk 2 is mounted on the shaft above the block .9 and is provided with teeth corresponding to the teeth w and is spring-held in engagement with the teeth w by suitable means, such as a spiral spring 3, which surrounds the shaft on and engages a collar 4. A projection 5 is formed on the ratchet-disk 2 and is suitably engaged by a driving-arm 6, the opposite end of which is secured to a pin or projection 7 extending outwardly from the rotating arm e.

The length of the throw of the arm 6 is so regulated as to move the ratchet-disk 2 through a portion of a revolution of a size depending on the number of forks used on the device that is to say, a quarter of a revolution if there are four forks or a sixth of a revolution if there are six forks. Consequently it will be seen that the block 8 will be rotated an equal distance, but will always be rotated in the same direction, owing to the ratchet connection which it has with the disk 2. The effect will therefore be to cause the arms 32 and the arms q and the parts to which they are secured to rotate inthe direction indicated by the arrow in Fig. 2.

It may here be mentioned that the upper ends of the arms q are pivotally secured to projecting pieces 8, which are formed on a slidable collar 9. (Shown in detail in Fig. 6.) This collar has a downwardly-extending semicylindrical portion 10. A stationary collar 11 is provided on the shaft on below the collar 9 and is formed with an upwardly-exending semicylindrical portion 12, corresponding in shape to the portion 10. A strong compression spiral spring 13 extends between the collar 11 and the under side of the collar 9, and it will be seen that as long as these two collars are held apart on the shaft on the forks will be held approximately perpendicular to the armsp and q, or, in other words, in a position in which they would support a sheaf. If, however, the collar 9 through any means were forced to slide down the shaft m, so that the two semicylindrical particles 12 and 10 would overlap each other and together surround eaeli one-half of the same ortion of the shaft, or, in other words, would be on a level with each other, the result would be that the forks would be tilted down into such a position that the sheaves would slide off their ends. This is what actually takes place in the machine, the operation being as follows:

At each stroke of the arm 6 one of the rollers t runs up on the projecting portion 14: of the stationary cam a, and thereby throws out the arm 10, the fork secured thereto, and consequently the arm 9, into such a position that the upper portion of the sheaf, which is at the same time being thrown off the table a, will be caught by the fork as the roller falls back into its normal position down the steep portion 15 of the cam. It will here be explained that spiral springs 16 extend between the arms 2 and suitable portions of the rotatable block 8 and are adapted to pull the arms back into their normal position as the rollers pass over the cam. The next stroke of the arm 6 rotates the forks, and thereby carries the sheaf away from the front of the table and brings the next fork into position to catch the next sheaf in a similar manner. Immediately after the last fork has engaged its sheaf the two semicylindrical portions 10 and 12 will come into the position in which the upper one can slide down on the shaftinto the position shown in Fig. 6 without being prevented by thelower one. The weight of the four sheaves acting on the forks and through the arms q will produce this result, and accordingly the sheaves will all be dropped to the ground in the upright position, so as to form a stock or shock, Immediately the weight of the grain is removed from the forks the strong spiral spring 13 will force the collar 9 up again into the position shown in Fig. 3, thereby causing the semicylindrical portion 10 to clear the similar portion 12 and enabling the rotatable parts to continue to rotate as before at each stroke of the arm 6. The operation then continues so long as the binder continues to throw out the sheaves.

It will now be seen that I have devised an extremely simple and cheap attachment for binders which with a very small additional amount of power will save the labor required in stooking the sheaves by hand. The device has the further advantage of being applicable to most of the ordinary forms of binders at present in use with very slight changes and is simple and cheap in construction, so that any farmer can readily understand the method of assembling and adjusting its various parts.

It is to be understood that in practice I may make certain variations in the details of construction of the device without departing from the spirit of my invention. I therefore do not wish to limit myself to the exact form of the device shown herein.
